Chapter 13, Problem 157AE

(a)

Interpretation Introduction

Interpretation: The $\text{pH}$ of the given solution is to be calculated and relation between the $\text{pH}$ of iron(II) nitrate and that of iron(III) nitrate is to be stated.

Concept introduction: The $\text{pH}$ of any solution depends upon the total $\left[{\text{H}}^{+}\right]$ concentration.  Metal ions with higher charge are more acidic than the metal ions with lower charge.

To determine: The $\text{pH}$ of the given solution.
